This is a proof-of-concept, 3-bit Jacquard-style, all-mechanical punch card reader. The design was inspired by designs in a textbook called "The Mechanism of Weaving" by T.W. Fox (it's about 100 years old, but I found a copy on Amazon), and adapted to work within the limitations of my Makerbot ToM printer. It is a single-cylinder, single-acting, positive-action device. This design could readily be adapted to a higher number of 'bits' (needles) by re-designing only a few parts. With minor modifications, it should be suitable to mounting over a miniature loom, with the bottom eyes of the hooks lifting healds or warp threads directly. This is probably as impractical as it sounds.

This is a proof-of-concept for building a simple electromechanical computer. Using a series of punch-cards, it can compute the fibonacci sequence (or other simple algorithms). Additional registers could be added to support more complex operations.

This is version 2.0 of a 3-digit, base-10 register for an electromechanical computer I'm working on. It is stepper-driven, and works like a 3-digit counter, counting from 000-999 before rolling over. When all three digit wheels read '0-0-0', 3 reed switches will close and a circuit will be completed to detect the condition.

This one uses fewer parts and has at least been slightly tested. It also has larger digit surfaces for better visibility, and comes with printable labels!

This is designed to be screwed into a wall so that you can hang a wine glass from it and free up valuable cupboard space. This was designed to accomodate some comically large wine glasses given to us by my mother-in-law, so it should be pretty one-size-fits-all (May not work with wine glass that can hold an entire bottle featured in sky-mall. YMMV.)

This is designed particularly for city-dwelling ladies (or adventurous men). It slips over the tip of the heel to protect it en route to your final destination. You can apparently buy these for $10 from a number of places. Take that Big High-Heel Protector!

They're designed for heels with a roughly .45" square tip (the test pair they were designed for - I don't really know what other sizes are out there).

Now updated to be slightly rounded on the rear/side edges, to decrease scuffing.
